FIELD: inorganic chemistry, metals. SUBSTANCE: technical tellurium is dissolved in hydrogen peroxide following by boiling of prepared acid at tellurium addition and isolation of purified tellurium by electrolysis. Solution purified by ionic exchange is crystallized before electrolysis, and mother liquor is recovered at dissolving stage. Mother liquor formed by electrolysis is recovered at the stage of potassium tellurate preparing up to the content of potassium tellurate in solution 50-60 g/l. EFFECT: improved method of tellurium purification. 2 dwg
